Cookies Policy

Cookies are small pieces of information that a website or service can store in your browser. They can support functions such as remembering a preference, maintaining a session, or measuring visits.

Browser local storage and session storage are different storage mechanisms. A website can also receive technical request data without using any of these mechanisms.

The calculator code processes entries in your browser and does not require an account cookie. We do not intentionally configure Google Analytics to collect the values you type into calculators.

Changing or reloading a page may clear calculator entries. Browser features such as form restoration can behave differently across devices.

We use Google Analytics 4 with measurement ID G-NG65GQNVDF. Google Analytics may set analytics cookies or use similar identifiers to distinguish browsers, measure visits, understand engagement, and prepare aggregated reports about how the website is used.

Common Google Analytics cookies include _ga and _ga_<container-id>. Google controls the exact cookie names, values, and lifetimes, and those details may change. Google Analytics cookies are not required for the core calculator functions.

• _ga: commonly used to distinguish browsers for analytics measurement.
• _ga_<container-id>: commonly used to maintain session or measurement state for a specific Google Analytics property.
• Other Google or infrastructure cookies may appear if our configuration or service providers change.

Google Analytics can provide information such as page views, engagement, referring pages, browser and device categories, approximate location derived from network information, and technical performance signals.

We use this information to understand which pages and tools are useful, identify usability or technical problems, and improve the website. We do not use Google Analytics as a storage system for calculator inputs or contact-message contents.

The hosting environment handles page requests and may retain technical logs or use storage for delivery and security. These behaviours depend on the infrastructure configuration.

An IP address or error in a server log is not itself a cookie. Contact us if you need clarification about an item you see in your browser's site-data controls.

The contact form prepares a message in your email application. It does not use a website cookie to save or submit your message.

Your email application may store a draft and your email provider may use its own cookies when you visit its service. Those activities are governed by that provider's settings and privacy information.

Sharing buttons open a destination service when selected. That service may use cookies or recognise an account that is already signed in.

Reference links also take you to independent websites. This policy does not control storage used by those destinations.

You can use your browser's privacy settings to inspect, delete, or block cookies and site data. Blocking Google Analytics cookies may reduce the accuracy of our traffic reports but should not stop the core calculators from working.

For step-by-step help, follow the instructions for Chrome cookie controls or clearing Firefox site data. You can also use browser privacy features or extensions that block analytics requests.

• Open your browser's Settings and find Privacy, Security, Cookies, or Site Data.
• Search for this website's domain to inspect stored items.
• Remove individual analytics cookies or clear the domain's stored data.
• Review third-party-cookie and tracking-protection controls if you want to limit analytics technologies across websites.

Our core calculations do not depend on Google Analytics cookies. Blocking analytics storage may reduce the information available in our traffic and engagement reports.

Blocking or clearing other browser data can affect external services, saved settings, or sign-in sessions on other websites. Check which domains and storage items you are clearing before proceeding.

Analytics technologies may require consent before they are used in some jurisdictions. Applicable consent and opt-out requirements depend on the visitor's location, the services enabled, and the law that applies.

Browser controls remain available regardless of whether a separate website consent mechanism is present. If we add advertising, personalization, or additional tracking services, this policy will be updated to describe them and their controls.

A session cookie is generally limited to a browser session, while a persistent cookie has a specified lifetime. Google controls the expiry settings for Google Analytics cookies, and those settings can change based on configuration and service updates.

Your browser's site-data controls can show the cookies currently stored for this website and, in many browsers, their expiration information.

Google Analytics is provided by Google. Analytics information is transmitted to Google so that Google can process it and provide measurement and reporting services to us.

For more information, review Google's Privacy Policy and Google Analytics privacy information.

We will revise this page when relevant cookie, analytics, advertising, or browser-storage practices change and update the date at the top. Questions about personal information are also covered in the Privacy Policy.
